NOTES AND RECOMENDATIONS:

Bn this case after the load had been s+itched to reser*e phases and the *oltage on the priorit phase regenerated the load +ill return to the priorit phase and thus sustained o*erload of the reser*e phase +ill be excluded; not to bring%in 6to exclude7 the phase priorit if the &E'%()1 backs up the essential load of inconsiderable *alue because the s+itching of this load to reser*e phase +ill not *irtuall produce an effect on phase loading; to select different priorit phases for different single%phase loads in order to a*oid phase o*erloads +hen se*eral de*ices are energized from the one and the same mains. Bnternal blocking for sticking of output built%in rela contacts is pro*ided in the &E'%()1. lso the &E'%()1 performs the monitoring of the magnetic starter po+er contact position in external circuit and is blocking the po+er contacts for their sticking 6the 12 terminal is used, see 5B8B DB89 M27.
